Hi, I'm integrating the FMCOMMS3 with an unsupported board. So far, I'm able to see the rx_frame signal go high and read received data, but I'm having some issues sending SPI commands. On the FMC connector, I only see spi_mosi, spi_miso,spi_csn, and spi_clk. From the HDL reference designs, I see that spi_csn is just slave select, but where is spi_enable? The gpio_enable is for the chip itself, but is that also used for SPI?
